Pricing policy

Overview#

Unlike traditional billing methods, DID Spaces charges based on usage, with the unit of billing referred to as a unit. Following successful Subscribe to DID Spaces, a certain fee will be charged daily based on the number of units used by the user.

It is worth noting that the Default Space created by DID Wallet (which is a gift from ArcBlock's official DID Spaces service to all wallet users) will be given 10 units for free (note that this may change as the company policy changes), even if you upgrade it for a fee, the given units will not disappear.

Chargeable items#

DID Spaces will convert into different units based on the stored project, here is the conversion table (please note that projects may be updated in the future):

Chargeable items	Number of units	Explanation
1 native app	* 1	Each connected native application (such as DID Wallet, Aistro), unit number + 1.
1 application backup	* 1	Every time an app is backed up, the unit count increases by 1.
Components in one application	* Number of components	If there are a total of 5 components under this application, with 3 components writing data to DID Space, then the unit count + 3.
1 GiB of storage space	* 1	Round up, every 1 GiB, unit number + 1. If less than 1 GiB, billing will be calculated as 1 GiB.
1 Profile	* 1	Each DID Wallet Profile contains one additional unit.

Example: If you are in a certain day

• Connected DID Wallet (+1 unit)
• Backed up 5 applications (+ 5 units)
• Wrote data with 3 components to DID Spaces (+ 3 units)
• Storage space used 8.88 GiB (+9 units)

So you need to pay a total of (1 + 5 + 3 + 9 = 18) units of fees.

If your DID Space happens to be the Default Space, then you only need to pay for 8 units (18 - 10, 10 units are free bonus units).

Declaration#

The free units and pricing items we give to Default Space are not set in stone, they will change with changes in company policy.
